Abstract :
The bit-error-rate (BER) improvement of partial-response continuous-phase-modulation (PRCPM) signals in fast Rayleigh fading that is achieved by adding a postdetection decision-feedback equalizer (DFE) to cancel the effect of intersymbol interference of one adjacent bit is investigated. A closed-form expression for the average probability of error in fast fading is derived for one-bit differential detection with decision feedback. Numerical results are presented to compare the BER performance of one-bit differential detection with and without feedback equalization. It is found that, in general, adding DFE improves the BER performance in fast fading
